Deportivo Wanka's decision to stage their home matches in the mining town of Cerro de Pasco almost certainly the world's highest venue for professional football caused further controversy after they held Universitario 2-2 on Wednesday.

"We could have won but it's inhumane to play in Pasco fumed visiting coach Reyna after his team faced hail rain and near-freezing temperatures as well as the suffocating altitude.

Goalkeeper Juan Flores added: "Tell (Peruvian Football Federation) president Manuel Burga and the federation to come and play in Pasco."

Wanka are based in the Andean city of Huancayo which is at around 2300 metres (7544 feet) above sea level and around 200 km away but have temporarily moved their base to Pasco in a bid to escape relegation.

The Peruvian league says the move is allowed in the rules which permit teams to use alternative venues.

Uruguayan striker Ernesto Zapata headed Wanka in front before Juan Vargas from a penalty and Piero Alva gave Universitario a 2-1 halftime lead. Pablo Medina equalised for Wanka in early in the second half.

Universitario dropped to third place and stayed 10 points behind leaders Sporting Cristal in the championship's second stage.

Cristal were held 2-2 at Sport Boys while Union Huaral's 2-0 win over Deportivo San Martin lifted them to second.
